The value of c is 0 guaranteed by the Mean Value Theorem for Integrals for the function 2x+1 on the interval [3,6].
What is Mean Value Theorem?Mean value theorem states, roughly, that for a given planar arc between two endpoints, there is at least one point at which the tangent to the arc is parallel to the secant through its endpoints.
Given.
Function is 2x+1 on the interval [3,6]
f(x)=2x+1
f(x) continuous on [3, 6] and differentiable on (3, 6) so the MVT applies here.
f(3)=7
f(6)=13
Average rate of change of f on [3,6]
= (13-7) / (6-3) = 6/3=2
To find the c-value guaranteed by the MVT, such that the instantaneous rate of change when x = c is 2, we differentiate, set f'(x) = 2, and solve:
f'(x) = 2 and x = 1.
c = 0 is the only c-value in the interval at which the instantaneous rate of change = the average rate of change.
Hence, the value of c is 0 guaranteed by the Mean Value Theorem for Integrals for the function 2x+1 on the interval [3,6].

Cari is searching online for airline tickets. Two weeks ago, the cost to fly from boston to denver was $220. Now the cost is $295. What is the percent increase? What would be the percent increase if the airline charges an additional $50 baggage fee with the new ticket price?
The percent increase with the additional baggage fee for airline would be $125 / $220 x 100% = 56.82%.
What is meant by the term percentage?A number can be expressed as a fraction of 100 using a percentage. It may be computed by dividing the number by the total and multiplying by 100. It is commonly represented by the sign "%". The percentage of men, for instance, would be 25/100 x 100, or 25%, if there were 100 persons in all.
In a variety of areas, including statistics, finance, and education, percentages are often employed. For instance, in finance, percentage increase in stock prices are used to gauge a market's or company's success. In education, grades are frequently given as percentages to represent class marks.
How to solve?
The increase in the cost of the ticket is $295 - $220 = $75
The percent increase is $75 / $220 x 100% = 34.09%.
If the airline charges an additional $50 baggage fee, the new ticket price would be $295 + $50 = $345.
The increase in the cost of the ticket with the additional baggage fee would be $345 - $220 = $125.
The percent increase with the additional baggage fee would be $125 / $220 x 100% = 56.82%.

Greg works two part time jobs. One job is at a gas station that pays $12 an hour and the other is delivering groceries for $15.50 an hour. Between the two jobs Greg wants to earn at least $390 a week. Let x be the number of hours he works at the gas station and let y be the number of hours he works delivering groceries. Write an inequality that models this situation.
The required inequality model for this situation is 12x + 15.5y ≥ 390.
What are inequalities?
The mathematical expressions with inequalities are those with unequal sides on both sides. Unlike equations, we compare two values when we work with inequality. The equal sign is substituted between by the less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
"A connection is termed an inequality if two real numbers or algebraic expressions are connected by the symbols ">,"< "," <="," or ">=."
For instance, x>3 (x should be greater than 3)
If there is just one variable, the inequality is said to have an open sentence.
Instance: x 6 (x is less than 6)
Double Inequalities: If the statement demonstrates a double relation between the expressions or the numbers, the inequality is said to be a double inequality.
Instance: 3 x 8 ( x is greater than or equal to 3 and less than 8)
Given, the gas station pays $12 an hour and delivers groceries for $15.50 an hour.
And, x be the number of hours he works at the gas station and let y be the number of hours he works delivering groceries.
Then, total earnings in gas station = 12x
total earnings for delivering groceries = 15.5y
So, based on the given inequality condition
12x + 15.5y ≥ 390
Hence, the required inequality model for this situation is 12x + 15.5y ≥ 390.

What is meant by a function?A function from a set X to a set Y in mathematics assigns to each element of X exactly one element of Y. The domain of the function is the set X, and the codomain of the function is the set Y.
The first known attempt to define function can be found in the writings of Persian mathematicians Al-Biruni and Sharaf al-Din al-Tusi. The concept of a function was codified in terms of set theory at the end of the nineteenth century, which substantially expanded its realms of applicability. The range of possibilities for variation or the distances between them: pricing for various grades of steel; a variety of designs. a thing's operation or action's reach or extent: accessible to the eye. a projectile's range is how far a weapon can or will shoot it.

What is the average rate of change of this function on the interval from x = 1 to x = 3? f(x)=10(2)x Enter your answer in the box.
Answer:
30
Step-by-step explanation:
The way to figure out the average rate of change is to divide the change in f(x) and divide that by the change in x. A formula for this is [tex]\frac{f(x_{1})-f(x_{2})}{x_{1}-x_{2}}[/tex]
1.) By this definition, we need to figure out our x1 and x2. We can say the x1 = 3 and x2 = 1
2.) Next, we plug it into the formula. We will get [tex]\frac{f(3)-f(1)}{3-1}[/tex].
3.) If we simplify, we will get 10(2)^3 - 10*2 divided by 2, which is equal to 10*4 - 10 = 30.

Combine two copies of the trapezoid to make a parallelogram. (b) Subdivide the trapezoid
into two triangles, one with base b and one with base a.
The two possible ways to find the area are -
A = (1/2) × {a + b} × {h}A = {b x h} - (1/2) x {(b - a} x h}What is trapezoid?
A trapezoid, also known as a trapezium, is a flat closed shape having 4 straight sides, with one pair of parallel sides.
Area : ½ x (sum of the lengths of the parallel sides) x perpendicular distance between parallel sidesPerimeter : sum of lengths of sides of trapezoidNumber of vertices : 4Number of edges : 4Properties : Convex polygonType : QuadrilateralSum of interior angles : 360°We have a trapezoid.
Now, we can find the area in two ways -
[1] -
A = (1/2) × {a + b} × {h}
[2] -
A = {b x h} - (1/2) x {(b - a} x h}

which property in math is (n+2.9)+0.3=n+(2.9+0.3)
Notice that the order the numbers are written on both sides is the same:
n, then 2.9, then 0.3

10/8 = n/10 proportions please
[tex]\displaystyle n=\frac{25}{2}[/tex]
Step-by-step explanation:A proportion is a set of equal ratios.
Cross Multiplication
The most common (and easiest) way to solve a proportion is cross multiplication. To cross-multiply, multiply the numerators by the opposite denominators. So, you are multiplying across the proportion.
After cross multiplying you get 10*10 = 8n.
Solving For n
Now, we can use algebra to find n.
100 = 8nJust, divide both sides by 8.
[tex]n=\frac{100}{8}[/tex]Then, simplify.
[tex]n=\frac{25}{2}[/tex]Checking The Answer
To check your answer all you have to do is plug n back into the equation.

find the slope and y-intercept of the line 3x - 5y = 15
The slope of the given line, 3x - 5y = 15, is 3/5 and the y-intercept is -3
Determining the slope and y-intercept of a lineFrom the question, we are to determine the slope and y-intercept of the given line.
The given line is
3x - 5y = 15
To determine the slope, we will write the equation in the slope-intercept form of a line.
The slope-intercept form of a line is given as
y = mx + b
Where m is the slope
and b is the y-intercept
Now, we will express the given equation in this form
3x - 5y = 15
-5y = 15 - 3x
Divide through by - 5
y = -3 + 3/5x
y = 3/5x - 3
By comparing to the slope-intercept form of a line,
m = 3/5

if you have a square with a length of 5x, write an expression for the perimeter of the square.
The perimeter of a square with a length of 5x can be represented by the expression 45x. This is because the perimeter of a square is equal to the length of any side of the square multiplied by the total number of sides, which is 4 for a square. So, for a square with a length of 5x, the perimeter would be 45x, or 20x.
